A crate of fruit with a mass of 31.0 kg and a specific heat capacity of 3600j/(kgxk) slides 8.40m down a ramp inclined at an angle of 39.4 degrees below horizontal.  if the crate was at rest at the top of the incline and has a speed of 2.85 m/s at the bottom, how much work wf was done on the crate by friction? if an amount of heat equal to the magnitude of the work done by friction is absorbed by the crate of fruit and the fruit reaches a uniform final temperature what is its temperature change?

First law of Thermodynamics

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of energy. Energy transfer is something that we encounter in day-to-day life. Automobiles, chemical reactions, refrigerators, and power generators work on the basis of thermodynamic principles.
